Habitat and environmental monitoring represent a class of sensor network applications with enormous potential benefits for scientific communities and society as a whole. Habitat monitoring permits researchers to obtain detail measurements of a particular environment in an unobtrusive manner. Sea bird colonies are notaries for their human disturbances. Sensor networks represent a significant advance over traditional invasive methods of monitoring. In our system we used heterogeneous network architecture for habitat monitoring. The architecture has been tested and analyzed by using the discrete event simulation framework called QualNet 4.5.1. In this architecture we are using the present wireless technologies like Wi-Fi, WiMax and ZigBee network. We designed the heterogeneous network and developed a traffic generator protocol for the sensor network called sensor bit rate (SBR).Which is stochastic traffic generation models are used to analyze the performance and behavior of the SBR traffic in habitat monitoring architecture.
